摘要:
The combustible component of a gas stream of low heating value is combusted using less than a stoichiometric amount of oxygen in the presence of an oxygenation catalyst and the heat energy in the combusted gas is utilized, for example, by expansion in a gas turbine.
摘要:
A catalyst for cracking gasoline feedstock with greater selectivity to gasoline production and greater metals tolerance comprising an alumina-aluminum phosphate-silica matrix composited with a zeolite having cracking activity.
摘要:

摘要:
A process for epoxidizing an alpha-olefin by adding an alpha-olefin and an oxygen transfer catalyst to a hydroperoxide stabilized with barium oxide.
摘要:
A method of homopolymerizing a 1-olefin to a product including the trimer and tetramer by utilizing boron trifluoride under pressure in the presence of a suspended particulate adsorbent material. For example, 1-decene is homopolymerized at a temperature of about 25.degree. C. in the presence of a suspension of about two weight percent silica and boron trifluoride at a pressure of 125 psi.
摘要:
A process for hydrogenating hydrocarbons which comprises reacting a hydrocarbon with hydrogen in contact with a layered complex nickel silicate catalyst which has been reduced in a hydrogen atmosphere, oxidized in an atmosphere containing molecular oxygen and then again reduced in a hydrogen atmosphere.
摘要:
A process for cracking gasoline feedstock with superior selectivity to gasoline production and greater metals tolerance wherein said gasoline feedstock is brought into contact with a fluid cracking catalyst comprising a zeolite dispersed in a magnesia-alumina-aluminum phosphate matrix, wherein said matrix has outstanding thermal stability.
